[Feature Request]: Render Mermiad

[anhnhdo]

Bug Description

Support Mermaid Rendering in Teams Agents SDK Responses

Scenario

AI Agents frequently generate Mermaid diagrams to explain workflows, business processes, architectures, and decision trees.

Today, when an agent returns Mermaid syntax, Microsoft Teams displays it as plain text rather than a rendered diagram.

Example:

flowchart TD
    User --> Agent
    Agent --> KnowledgeBase
    Agent --> ExternalSystem
    Agent --> Response

Loading

Current Limitation

Teams Agents SDK does not provide a built-in mechanism for rendering Mermaid diagrams generated by agents.

Developers currently need to:

• Convert Mermaid to images before sending
• Host external rendering pages
• Build custom client-side rendering solutions

These workarounds increase complexity and reduce the usefulness of AI-generated visual content.

Proposed Enhancement

Allow Teams clients to automatically render Mermaid blocks returned by AI agents.

Possible implementations:

• Support Mermaid code blocks in agent responses
• Support Mermaid rendering within Adaptive Cards
• Support Mermaid rendering in Loop components generated by agents
• Provide a Teams SDK rendering component for Mermaid content

Benefits

• Better AI-generated visual explanations
• Improved user experience
• Reduced implementation effort
• Richer agent interactions inside Teams

As AI agents increasingly generate structured visual content, native Mermaid rendering would significantly improve the Teams agent experience.
